Re: SHADOWING-IMPORT doesn't
I suspect randomness: The bug Jeff@aiva.edinburgh.ac.uk reports
just bit me a couple of hours ago. And is funnier than it seems.
I loaded Doug Rand's defsystem package and a package of mine, called
kcl-edit. There exist symbols defsystem:defsystem and kcl-edit:ed.
During loading of the defsystem package, the symbol 'defsystem gets
interned accidentally in 'user. Of course, 'ed is already in 'user
Now, (shadowing-import 'kcl-edit:ed) works. (shadowing-import
'defsystem:defsystem) doesn't. Same for 'sloop:sloop.
My impression was that the package qualifier was being used as a
symbol somewhere during the translation and it was triggering the
problem (= symbols of the form 'x:x would fail; symbols like 'a:b
had a chance to work.) Jeff's example disproves the hypothesis,
